使用YouTube上的机器人播放音乐而无需下载文件 [英] Playing music with a bot from Youtube without downloading the file
问题描述
在不将歌曲下载为文件的情况下,如何使用Youtube上的不和谐机器人播放音乐?
How would i go about playing music using a discord bot from Youtube without downloading the song as a file?
我已经看过其中包含的音乐bot在discord.py文档中,但是该bot将文件下载到目录中。有什么办法可以避免这种情况?文档示例中的代码:
I've already had a look at the included music bot in the discord.py documentation but that one downloads a file to the directory. Is there any way to avoid this? Code from the documentation example:
ytdl_format_options = {
'format': 'bestaudio/best',
'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
'restrictfilenames': True,
'noplaylist': True,
'nocheckcertificate': True,
'ignoreerrors': False,
'logtostderr': False,
'quiet': True,
'no_warnings': True,
'default_search': 'auto',
'source_address': '0.0.0.0' # bind to ipv4 since ipv6 addresses cause issues sometimes
}
ffmpeg_options = {
'options': '-vn'
}
ytdl = youtube_dl.YoutubeDL(ytdl_format_options)
class YTDLSource(discord.PCMVolumeTransformer):
def __init__(self, source, *, data, volume=0.5):
super().__init__(source, volume)
self.data = data
self.title = data.get('title')
self.url = data.get('url')
@classmethod
async def from_url(cls, url, *, loop=None, stream=False):
loop = loop or asyncio.get_event_loop()
data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download= not stream))
if 'entries' in data:
# take first item from a playlist
data = data['entries'][0]
filename = data['url'] if stream else ytdl.prepare_filename(data)
return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)
@client.command()
async def play(ctx, url):
voice = await ctx.author.voice.channel.connect()
player = await YTDLSource.from_url(url, loop=client.loop)
ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
推荐答案
下载它,只需在您的播放
功能中使用此代码n:
To play music without downloading it, simply use this code into your play
function :
ydl_opts = {'format': 'bestaudio'}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
info = ydl.extract_info(video_link, download=False)
URL = info['formats'][0]['url']
voice = get(self.bot.voice_clients, guild=ctx.guild)
voice.play(discord.FFmpegPCMAudio(URL))
这是每行的用途:
Here is what each line is used for :
-
ydl_opts = {'format':'bestaudio'}
:使用youtube_dl获得最佳音频
-
。YoutubeDL(ydl_opts)为ydl:
:初始化youtube -dl
-
info = ydl.extract_info(video_link,download = False)
:获取一本名为<$ c的字典$ c> info ,包含所有视频信息(标题,时长,上传者,说明等)。
-
URL = info ['formats'] [0] ['url']
:获取指向视频音频文件的URL
-
voice = get(self.bot.voice _clients,guild = ctx.guild)
:初始化一个新的音频播放器
-
voice.play(discord.FFmpegPCMAudio(URL) ))
:播放正确的音乐
ydl_opts = {'format': 'bestaudio'}
: get the best possible audiowith youtube_dl.YoutubeDL(ydl_opts) as ydl:
: initialize youtube-dlinfo = ydl.extract_info(video_link, download=False)
: get a dictionary, namedinfo
, containing all the video information (title, duration, uploader, description, ...)URL = info['formats'][0]['url']
: get the URL which leads to the audio file of the videovoice = get(self.bot.voice_clients, guild=ctx.guild)
: initialize a new audio playervoice.play(discord.FFmpegPCMAudio(URL))
: play the right music
但是,从URL播放音频而不下载会导致已知问题解释 此处
要对其进行修复,只需添加一个变量,例如 FFMPEG_OPTIONS
其中将包含FFMPEG的选项:
However, Playing audio from an URL without downloading it causes a known issue explained here
To fix it, just add a variable, for instance, FFMPEG_OPTIONS
which will contain options for FFMPEG:
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
创建变量后,只需添加一个 FFmpegPCMAudio
方法的参数:
Once you've created the variable, you just have to add one argument to the FFmpegPCMAudio
method:
voice.play(discord.FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
